JOHN C. SEGER, OF GREENBRIER, ALABAMA.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 51 1,465, datedDecember 26, 1893. Application filed June 26, 1893- Serial No; 478.887-(No model.)

To all whom it may concern.-

Be it known that I, JOHN G. SEGER, a citizen of the United States,residing at Greenbrier, in the county of Limestone and State of Alabama,have invented a newand useful Nut-Lock, of which the following is aspecification.

My invention relates to improvements in nut-locking devices especiallyadapted for railroad rails at the joints between contiguous rails, andthe objects in view are to provide simple and efficient means which canbe readily detached and applied to facilitateadjustment, repair, &c.

Further objects and advantages of my invention will appear in thefollowing description and the novel features thereof will beparticularly pointed out in the appended claim.

In the drawings-Figure 1 is a perspective View of a nut-locking deviceembodying my improvements. Fig. 2 is asimilar view showing the lockingplate elevated to release the nuts. Fig. 3 is a transverse sectionalview.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates the meeting ends of two railroad rails, 2-2 the usualfish-plates which are arranged upon opposite sides of. the joint, 3 thetransverse bolts by which the fish-plates and rails are connected, and 4the nuts which are threaded upon the-extremities of such bolts.

5 represents a pivotal locking plate, which is pivoted at one end toswing in a vertical plane, and is provided at its free end withfastening devices hereinafter explained and is further provided with aseries of rectangular notches 6 which are spaced to agree. with thepositions of the bolts and nuts and are designed to fit over the latterwhen the looking plate is in its normal or horizontal position.

In order to reduce as much as possible the weight of the locking plateto facilitate its manipulation and also to save material and thereforereduce the cost of manufacture, I prefer to make the locking plate of awidth which exceeds only slightly the width of the It is the commonpractice to use washer plates in connection with looking devices ofVarious kinds, such washer plates being perforated to receive the boltsand being held in place by the nuts, and in my device it is necessary toemploy a stationary plate to which one end of the locking plate may bepivoted and also to employ suitable means for receiving and securing thefree end of such locking plate when in its normal or operative position,but in order to reduce the weight and expense of manufacture I avoid theuse of a continuous washer plate and employ a pivot plate 9 and a catchplate 10 which are independent of each other and may be arranged at anydesired interval, to suit the. The pivot plate length of the lockingplate. 9, to one end of which is pivotally connected the locking plate,is provided at the opposite end with a perforation to receive one of theterminal bolts, or the bolt at one end of the series and is secured inposition by means of the nut with which such bolt is provided. The catchplate is similarly perforated to receivethe bolt at the opposite end ofthe series and is held in place by the attached nut, such catch platebeing provided with a catch 11, consisting of a tongue provided at itsfree end with a flange or lip 12 to engage a shoulder 13 of the lockingplate. The free end of the locking plate is beveled to enable it toreadily enter the catch.

Having described my invention, what I claim is I In a device of theclass described, the combination with bolts and nuts, of a pivotallocking platearranged to swing in a plane parallel with that of thenuts, and a. spring: catch arranged to engage the free end. jofthe myown I have hereto aifixed my signature in looking plate when the latteris in its operthe presence of two witnesses.
